WebFeb 12, 2024 · A photometer indicates the photoelectric detector that measures the intensity of light. Spectrometer: It produces a desired range of wavelength of light. First a collimator (lens) transmits a straight beam of light (photons) that passes through a monochromator (prism) to split it into several component wavelengths (spectrum). Webphotodetector: [noun] any of various devices for detecting and measuring the intensity of radiant energy through photoelectric action.
WebThe light that passes through the flow cell enters the photodetector (photodiode) and is converted into an electrical signal corresponding to the intensity of the light, which is processed as absorbance. A UV-visible detector with a D2 lamp and a tungsten lamp is suitable for monitoring not only ultraviolet but also visible light. WebLIGO's optics system consists of lasers, a series of mirrors, and a photodetector (a device that measures varying light levels). In order to measure a movement thousands of times smaller than a proton, LIGO's …
